I have used Bitcoin over lightning in a way that wouldn't be faster, secure, or cheaper. It could be made more convenient if Apple Pay allowed me to pop it up, but that's not a fundamental issue with the technology. The benefits of using it are no rent-seeking middle-men, increased privacy, and the underlying currency that provides a non-inflationary monetary policy. Within the last 30 days I've used it to buy burgers and was even subject to sales tax.

And about the volatility comment, "volatility" is measured according to a specific exchange rate and can't be measured when you haven't defined a baseline. Bitcoin has high volatility with respect to gold but has trended to having more upward volatility vs downward volatility (whereas the dollar is mostly down).
